What is the purpose of the pump in a spray system?

The purpose of the pump in a spray system primarily revolves around generating system flow. In this context, the pump serves as the heart of the system, driving the liquid from the supply source through the various components and ultimately to the nozzle where the liquid is atomized into a spray. Without sufficient flow generated by the pump, the system would be unable to deliver the liquid needed for effective spraying, leading to reduced performance and efficacy of the application.

While the other functions mentioned—maintaining suspension, directing flow and pressure, and determining droplet size—are essential in various aspects of a spray system, they typically rely on the flow generated by the pump to function effectively. The pump ensures that adequate pressure is maintained, which is crucial for achieving the desired spray characteristics. Thus, generating system flow is a fundamental and crucial operation within the spray system that underpins its overall effectiveness.
